Abstract
In one aspect of the present disclosure, a system and method are provided for pairing a network-enabled movable barrier operator with a transmitter. The method may include receiving a pairing request, retrieving a hashed version of the transmitter fixed code, verifying access authorization, and forwarding the hashed version of the transmitter fixed code to a movable barrier operator to allow the movable barrier operator to determine whether a new transmitter is authorized to control the movable barrier operator.
Claims17
A movable barrier operator apparatus comprising:
- a memory;
- communication circuitry configured to receive an add transmitter request from a remote computer via a network, the add transmitter request including a transmitter code comprising a hashed version of a transmitter fixed code;
- the communication circuitry configured to receive a radio frequency control signal from an unknown transmitter, the radio frequency control signal including a fixed code of the unknown transmitter;
- and
- a processor operably coupled to the memory and the communication circuitry, the processor configured to:
- store, in the memory, the transmitter code of the add transmitter request received from the remote computer;
- perform a hash function on the fixed code of the radio frequency control signal received from the unknown transmitter to obtain a hashed version of the fixed code of the radio frequency control signal;
- and
- determine whether to operate a movable barrier based at least in part upon whether the hashed version of the fixed code of the radio frequency control signal received from the unknown transmitter corresponds to the hashed version of the transmitter fixed code received from the remote computer.

A method for operating a movable barrier operator apparatus, the method comprising:
- receiving an add transmitter request from a remote computer via communication circuitry of the movable barrier operator apparatus, the add transmitter request including a transmitter code comprising a hashed version of a transmitter fixed code;
- storing, with a processor of the movable barrier operator apparatus, the transmitter code of the add transmitter request in a memory of the movable barrier operator apparatus;
- receiving, at the communication circuitry of the movable barrier operator apparatus, a radio frequency control signal from an unknown transmitter, the radio frequency control signal including a fixed code of the unknown transmitter;
- performing, with the processor of the movable barrier operator apparatus, a hash function on the fixed code of the radio frequency control signal received from the unknown transmitter to obtain a hashed version of the fixed code of the radio frequency control signal;
- and
- determining, with the processor, whether to operate a movable barrier based at least in part upon whether the hashed version of the fixed code received from the unknown transmitter corresponds to the hashed version of the transmitter fixed code received from the remote computer.

- and
- cause the communication circuitry to transmit a radio frequency signal including the fixed code to a trainable transmitter to permit the trainable transmitter to learn the fixed code.
